Hey Guys,
Thanks to some pointers that Ron Minnich gave me a few weeks back, I've been able to debrick my Samsung 550 Chromebook. However, during the time I waited for my Bus Pirate I started thinking it might be nice to build my own Coreboot, with a SeaBIOS payload. Now I have a build, but flashing it with the ChromiumOS version of Flashrom (in the hope of not overwriting OTP areas) still gives me a brick. I haven't included the ME firmware or the descriptor, and I'm guessing this is the problem? If so, how can I extract these from my original copy of the BIOS (I see they are in there using fmap_decode, but using the syntax for extracting the BOOT_STUB in the VMX hacking doc on the Chromium website doesn't give me what I expected. Also do I need a VGA BIOS?
Thanks in advance.
